Canon 31
On performing sacred rites in home churches only with the blessing of the bishop.
We determine that clergy who liturgize or baptize in chapels located in houses should do so with the consent of the local bishop, so that if any cleric does not comply with this, he will be deposed.
Greek original
Τοὺς ἐν τοῖς εὐκτηρίοις οἴκοις, ἔνδον οἰκίας τυγχάνουσι, λειτουργοῦντας, ἢ βαπτίζοντας κληρικούς, ὑπὸ γνώμην τοῦτο πράττειν τοῦ κατὰ τόπον ἐπισκόπου, ὁρίζομεν· ὥστε, εἴ τις κληρικὸς μὴ τοῦτο οὕτω παραφυλάξῃ, καθαιρείσθω.
